    摘要： The invention provides polyurethanes filled with carbon black, which are characterised by a high dielectric constant and high breakdown strength, and which are synthesised from polyalkylene oxides that have been produced by DMC catalysis. The compositions comprise polyether polyurethanes which are the reaction products of one or more polyisocyanates and one or more polyol components, the polyol components being comprised of a) polyalkylene oxides produced by DMC catalysis, and b) 0-50 wt. % of polyols free from catalyst residues, and B) 0.1-30 wt. % of carbon black.

    摘要： A thermoplastic molding composition suitable for the preparation of foam is disclosed. The composition comprises a thermoplastic resinous component and a foaming agent which includes A) (i) 0.01 to 4.8% alumina hydrate (aluminum hydroxide) in combination with (ii) 0.01 to 4.8% of an acidic additive or B) 0.01 to 4.8% of the reaction product of said (i) and said (ii), the percentages being relative to the weight of the composition to be foamed. The invention is based on the finding that the foaming of the composition does not lead to any significant reduction in molecular weight of the resinous component or to troublesome discoloration of the foam, even during its re-extrusion.
